Description

Technical Field

[0001] The invention relates to the technical field of motor stator production devices, in particular to an automatic motor coil winding device. Background Art

[0002] A motor is a rotating machine that converts electrical energy into mechanical energy. It primarily consists of a stator, which generates a magnetic field, and a rotating rotor. Under the influence of the stator winding's rotating magnetic field, current flows through the rotor's active edge, causing it to rotate under the influence of the magnetic field. The stator is composed of a frame, a stator core, and stator windings. The frame is the motor's outer casing, supporting the motor. The stator core, as part of the motor's magnetic circuit, is housed within the frame. Its outer wall is in contact with the frame, while the inner wall has slots to accommodate the stator windings.

[0003] With the advancement of technology, existing stator winding machines can realize automatic winding of stators, such as a motor stator winding device with Chinese patent publication number CN106487172A, which includes a frame, a winding mechanism installed on the frame, a grabbing mechanism, a first conveying mechanism, a second conveying mechanism and a driving mechanism for driving the grabbing mechanism to operate. The first conveying mechanism and the second conveying mechanism are respectively arranged on both sides of the winding mechanism. The winding mechanism includes a turntable for mounting a workpiece, a first motor for driving the turntable to rotate, a winder and a second motor for driving the winder to rotate. The grabbing mechanism includes a clamping assembly for clamping the workpiece and a first cylinder for driving the clamping assembly to move up and down. The clamping assembly includes a clamping part and a second cylinder for driving the clamping part to clamp or open. The motor stator winding device of this invention is used in motor stator assembly production, requires fewer workers to operate, reduces the labor intensity of workers, improves production efficiency, and greatly eliminates safety hazards existing in workers' winding operations.

[0004] Although this invention patent can realize automatic winding of the motor stator, in the actual winding process, the number of turns wound on the stator is fixed. When winding the stator, the enameled wires will stack on each other. At this time, although the number of enameled coils wound on the stator has not changed, the upper layer of enameled wire is not evenly attached to the lower layer of enameled wire, but a stacking phenomenon occurs. This will cause the length of the enameled wire actually wound on the stator to change, resulting in a mismatch between the actual performance of the motor and the designed performance, and the performance of the motor cannot be fully utilized.

[0005] To this end, we propose an automatic motor coil winding device to solve the above problems. Summary of the Invention

[0016] Through the above technical solution, by providing an arc - shaped transition section on each protruding part, the wiring operation of the enameled wire can be effectively carried out.

[0032] Sixth, in the present invention, when the winding of a stator is completed, the multi-stage electric push rod drives the discharge push plate to move upward. Before the discharge push plate contacts the stator, the trigger rod will push the shift block through the arc-shaped trigger part, thereby separating the two limit blocks from the stator. Then, the multi-stage electric push rod continues to drive the discharge push plate to move upward, pushing out the wound stator to achieve automatic unloading. BRIEF DESCRIPTION OF THE DRAWINGS

Compared with the prior art, the wear of the enameled wire 14 can be effectively reduced, and the surface of the enameled wire 14 can be prevented from being damaged during the winding process.

[0074] When the stepping motor 21 is working, the winding bracket 18 can be driven, and then the winding protrusion 23 can be driven. Since the end of the winding protrusion 23 and the output end of the stepping motor 21 are arranged in the same straight line in the horizontal direction, the winding protrusion 23 can rotate coaxially with the stepping motor 21, which is convenient for real-time adjustment of the enameled wire 14 on the winding protrusion 23.

[0075] During the winding process of the stator 34, the controller can control the wire feeding motor 13. As the winding progresses, the enameled wire 14 can be continuously fed to avoid pulling the enameled wire 14, which can effectively prevent the enameled wire 14 from breaking.

[0076] The stator 34 is placed in the mounting groove, and the compression spring 40 continuously squeezes the rotating ring 33, so that the two limit blocks 35 are always in close contact with the outer wall of the stator 34, clamping the stator 34, thereby effectively preventing the stator 34 from shifting during the winding process. Specifically, the rotating ring 33 can push the corresponding second triangular push block 37 through the first triangular push block 36, so that each second triangular push block 37 can move toward the stator 34, and the part where each limit block 35 fits with the stator 34 is made of rubber, so as to increase the friction between the two limit blocks 35 and the outer wall of the stator 34, and further improve the stability of the stator 34 during the winding process.

[0077] When the winding of a stator 34 is completed, the multi-stage electric push rod 31 drives the discharge push plate 32 to move upward. Before the discharge push plate 32 contacts the stator 34, the trigger rod 26 pushes the shift block 27 through the arc-shaped trigger part, thereby separating the two limit blocks 35 from the stator 34. Then, the multi-stage electric push rod 31 continues to drive the discharge push plate 32 to move upward to push out the wound stator 34.

[0078] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
